Question

I want to search a text in a table without knowing its attributes.
Example : I have a table Customer,and i want to search a record which contains ‘mohit’ in any field without knowing its column name.

Answer 1

You are looking for Full Text Indexing

Example using the Contains

select ColumnName from TableName 
Where Contains(Col1,'mohit') OR contains(col2,'mohit')

NOTE – You can convert the above Free text query into dynamic Query using the column names calculated from the sys.Columns Query

Also check below

FIX: Full-Text Search Queries with CONTAINS Clause Search Across Columns

Also you can check all Column Name From below query

Select Name From sys.Columns Where Object_Id = 
                   (Select Object_Id from sys.Tables Where Name = 'TableName')

Double-WildCard LIKE statements will not speed up the query.
